I decided to try Kubuntu (10.4 64bit) again today, it's been a few years since I last tried it. The installation went well, but now I don't seem to be getting past Grub. I get a message that says: Kernel panic - not syncing:VFS:Unable to mount root fs on unknown block(0,0) I tried to use the recovery mode option in grub but that gave me the same message.
View 9 RepliesI installed mythbuntu from a live CD on an old machine with an IDE hard disk just to play with it. It worked a treat, so I bought an Acer Aspire Revo R3610 and used dd to copy the old HD contents to the new one, and then gparted to resize the ext4 partition.
On boot I got - Kernel panic: VFS: Unable to mount root fs on unknown-block(0,0)
I checked every grub2 command and it all looked fine. I then tried booting the original kernel that the live CD installed (2.6.31-14) and it booted! I tried 2/6/31-17 again, and got the panic.
After much googling, I found a suggestion to do - sudo update-initramfs -k all -c -v and this worked.
Is this expected behaviour? One of the delights of Linux is that installs move smoothly between machines, but this one didn't. Was this due to the old machine using IDE and the new one AHCI SATA? How do I get an initramfs that's flexible and will boot smoothly on any given hardware?
When I load the live CD into my computer, the DVD drive spins very fast and then drops down to command lines with a kernel Panic. I have tried with the Final Release and with the Release Candidate. Because of this I cant even load up to the live CD enviroment.
It also mentions the name of my mother board in the code, the motherboard is a gigabyte G41M-ES2L and is brand new.
Could someone give some advice or help? Currently I dont have ubuntu installed on this computer as I went for a fresh install with vista.
In my internal disk i had installed 10.04 and 10.10. 2 days ago after a restart my system did not boot and i got the message: kernel panic:not syncing VFS unable to mount root fs on unknown block(0,0).
For 2 days i tried to solve the problem without success and today i installed 10.04 in the entire internal disk but the problem(message above mentioned) remains.
the result of the sudo fdisk -l command is this

The Fedora 11 Live CD was tested on a Dell and it is good. On the HP Pavilion a705w, with an Intel Celeron 2.93HHz w 760MB RAM, the install fails with kernel panic. The cd was burned on the HP.
A colleague suggested that the HP may not be compatible with the kernel. Are there startup settings that I might try to diagnose the panic issue? Perhaps there is a verbose boot up process that pauses so one can take notes?

I've been trying to get Ubuntu on my beloved 4 year old Acer desktop that's been chugging like a tank. However, after either a fresh install or upgrade, I would get the following error:"Kernel panic - not syncing: VFS: Unable to mount to root FS on unknown-block(0,0)".I've looked here and there, and one of the issues it would seem is the kernel not recognizing my hard drive if I'm correct. One of the suggestions was to upgrade the kernel however, I have no idea how to do such a thing if I can't get into the OS.

View 1 Replies View RelatedI've been using Linux for a few years, but this is my first time using Fedora. I installed it on an old computer last night and rebooted, and everything seemed good. I let it start to install updates, but after they were about half done I stopped it, turned the computer off, and went to bed. I know that was stupid of me, and I'm afraid it screwed something up because now when I boot I get the error "kernel panic-not syncing VFS:unable to mount root fs on unknown-block(0,0)".
When I looked up the error on Google it seems a lot of people get this after installing a kernel incorrectly, so could stopping the update in the middle perhaps screwed with my kernel? Could I simply chroot into the installation from the live CD and run 'yum install kernel26'?

View 1 Replies View RelatedI tried to upgrade Empathy from 2.28 to 2.30 via Synaptic but the upgrade always failed as there were some errors to do with the dependencies (libglib2.0* and others). The dependency issues were odd as it told me that Empathy wanted to install files that were older than the existing ones. So I decided to uninstall Empathy and all its dependencies, and re-install the whole (updated) package and it's dependencies from scratch via Synaptic. After the install, Ubuntu told me that there were broken packages and Update Manager kept on popping up asking me to run a partial upgrade to fix these broken packages. Well, the partial upgrade also failed (due to the same dependency issues , I suspect) so I decided that I'll run a full system update (as Update Manager had being bugging me prior to my failed Empathy upgrade). 486 Mb later, Ubuntu no longer wants to boot - it freezes on the splash screen.
When I start it in recovery mode, it spews out the various processes being loaded. Trying to run earlier kernels (2.6.31-19 / 17 / 14) from GRUB, in both normal mode and recovery mode does not seem to help.I am running Ubuntu 9.10, kernel 2.6.31-20-generic.
a) Is the problem to do with the kernel - did the update try to update the kernel as I note that there is a new stable release (2.6.33-2)? However, GRUB still indicates that the kernel is 2.6.31-20.
b) Would updating the kernel to 2.6.33-2 help? If so, how do I do this?
c) Is the problem, as I suspect, to do with the libglib* files? If so, how do I fix it?
I am trying to install Fedora 11 from the full DVD iso on a system using an Intel D945GNT motherboard with a dual-core 3.2GHz Pentium D installed. The installation hangs quite quickly and produces the error "Kernel panic - not syncing"... The previous line is something along the lines of "EIP: [something] intel_i915_configure() [something else]". I have tried many different kernel boot options, such as acpi=off, nolapic, nommconf, and the like, but to no avail. It seems as though this has something to do with a memory mapping conflict due to the allocation of video memory for the on-board graphics chip, but I'm not at all certain about that.
View 3 Replies View RelatedI have a system here that tends to have kernel panics during an linux installation, though I was able to perform a vista installation on the same hardware. Now I would like to ask what your suggestion for the cause of that problem is. Here a screenshot: [URL]
I suspect the hd to cause it:
-it is now over 7 years old
-smartctl displays over 16k read error and 0.5mio seek errors
(or are such high numbers normalfor that old disks?)
-the panic contains the string bad_area in the trace
But it might also be a RAM error, since the trace contains sth about page_fault and vista installs on the very same hdd and does not report any error messages (concerning the hardware, and I heard win doesn't complain about a bad RAM).

I learned yesterday that doing a massive upgrade on my system while moving was a BAAAD idea.The upgrade process was going along just fine, it was all downloaded and was actually installing that last time I saw it. I unplugged my laptop to move a bookcase out, and completely forgot to plug it back in. After I got back from moving a load, I found my computer was off. I tried to boot up, and I got an error that kind of freaked me out. It reads as follows:
Code:kernel panic not syncing vfs unable to mount root fs on unknown-block(0,0)I'm able to get to grub just fine, and my windows partition loads up just fine, but any of the linux kernels fail similarly when I attempt to load them.I'm sure that I can fix this, I just have no idea how. Probably has something to do with a live cd.
I had 9.10 installed on my IBM Lenovo Thinkpad, x301. I was performing updates as normal, and chose the Upgrade button to upgrade me to 10.04. Everything started fine, but upon reboot, no bueno, Kernel Panic!
The exact message was "Kernel Panic ubuntu - not synching VFS Unable to mount root fs".
I thought this was a grub issue. Since grub2 now is installed... But it was not. I think it ended up being a problem with some of my configuration files.
I have three kernels I tried:
1. 2.6.32-22
2. 2.6.31-21
3. 2.6.31-20
The first threw me into the kernel panic.
The second would hang on "init crypto disks"
The third would hang on "checking battery state"
I noticed (from reading another thread) that while these are loading up that you can click on alt-ctl-F1 thru F6 and get prompt. (I also had my home directory encrypted, thought that was part of the problem, but it wasnt).
Once I get passed the loging, I am able to poke around. I tried manually start Gnome via "sudo service gdm start", but it failed. Said it was missing a configuration file. Then I tried on "sudo dpkg-reconfigure gdm" and it would not work. Saying some configuration files are missing or broken. It also said something about dpkg --configure -a, I am assuming this configures everything...
So I tried "sudo dpkg --configure -a" And selected 'y' to every option. Which basically installs the package creators default settings, and viola! Works.
Just wanted to share that knowledge for the other stuck in the upgrade hell.
Normally I would just copy my files off and reinstall, but it was encrypted... Another headache. I guess good in case someone stole my laptop.
Remember try to "sudo dpkg --config -a"
I have a new acer machine which runs fine on 10.10 mythbuntu desktop livecd. Install seemed fine.
Then I ran an update and on reboot I get a kernel panic error. Research on this reveals it as a very deep subject which can consume many hours, so I opted to reinstall.
This time with ubuntu 10.10. I've tried different CDs, liveusb. Same errors.
So, the question is this - where do I concentrate my efforts - somewhere ubuntu doesn't like this machine, or grub. Does a reinstall overwrite the grub install too? Or do I have a bogus grub install I need to purge before I will get anywhere.
I ran into a strange issue after doing a preupgrade from Fedora 10 to Fedora 12: Preupgrade worked as described, I upgraded successfully to Fedora 12 and also worked 2 days without any (major) issue. Then I had some issues with firefox (malloc errors, couldn't start) so I thought I'll do it the "Windows Way" namely reboot, and then no chance to boot fedora. I was hit by a kernel panic saying "init not tainted 2.6.31.6-166.fc12.i686". I was able to boot in rescue mode using the preupgrade installer (still in the grub menu) but even chroot /mnt/sysimage gave me a "Segmentation fault".
I am not able to re-upgrade the system since the installer tells me (on vty3) "product Fedora version 12 found on VolGroup00-LogVol00 is not upgradeable". I also tried to reinstall the installed kernel as well as upstart (hint from [URL]) from the preupgrade repositories (using rpm --root /mnt/sysimage --force ...) but the kernel install failed with %post and %posttrans errors (signal 11). I also did fsck.ext3 for the lvm partition with no success. Does anyone have some additional hints how to recover? It's a 32 bit install on an Intel p4 with 2GB RAM.
i'm currently using puppy linux 431. and i want to replace it with fedora LXDE but i encounter this error upon booting using livecd.

I am trying to install Fedora on my computer but I am getting a kernel panic at liveCD boot after boot menu. It occurs to me for F13 and F14 (all x64, F14 x86 seems to boot fine but I'm trying to host a x64 guest OS on it so I need to get the x64 version to work)

Today I was upgrading my netbook with Ubuntu 10.10 on it to 11.04 via the Update Manager. I got a few errors and the Update Manager seemed like it wasn't continuing, so decided to exit it. It didn't respond so after a while I decided to restart the netbook. However the on/off/standby/restart, etc. button in the top right wasn't responding either, so I decided to force a shutdown with the power button on my netbook. Now Ubuntu doesn't start up, and gives me an error along the lines of:
Kernel panic - not syncing: Attempted to kill init! Pid: 1, comm: init Not tainted 2.6.35-28-generic #50-Ubuntu Now could I in some way repair my Ubuntu installation while still keeping the files I already have on my computer? Maybe via booting from a flash drive or something...?
I was able to copy the iso file and tried the installation however I stubbled upon the same problem I had when I tried installing Fedora 11.

My HDD is partitioned into three:

(hd0, 1) 120GB : /home

> First thing tried: preupgrade
Using this preupgrade setup happend and asked to reboot. However, upton reboot got locked in stage2. So this option was abondoned.
> Second thing tried: installation CDs
Using this method formatted (hd0,2) and installed FC12 on (hd0,2). However, did not change anything on (hd0,0). This still held all the upgrade information from the previous trial. Now, when I rebooted after the install there was a kernel panic with error "kernel panic not syncing vfs". Thinking it might due to the (hd0,0) partition and errors in my install, I abandoned this.
> Third thing tried: installation CDs
Using this method I formatted both (hd0,0) and (hd0,2). The install was similar to above but now (hd0,0) was also formatted and after install was empty. But upton reboot I still got the "kernel panic not syncing vfs" message. I dug through google and saw references to problems in grub.conf and lo behold there were problems with my grub.conf. I don't see the initrd line at all nor do I see the initrd*.img file in my disk. The grub.conf is:

I recently started to use Ubuntu in VWware player on my windows-XP. I installed ubuntu 10.04 few days ago, It was working fine.
Yesterday, I compile a new kernel, kernel 2.6.33 in my vmware ubuntu 10.04. Everything went well till I did reboot. before reboot I use the command "update-grub" to make it compatible to the new kernel. BUT... after rebooting, I have a problem in loading a grub correctly. it gives me following message " [2.149136 ]kernel panic - not syncing: VFS: unable to mount root fs on unknown-block(0,0)" and I can not proceed further. I have my all data on it. I also tried to boot it from live CD but unfortunately, I can't mount the hard disk on it in order to get those data from my old Ubuntu set up.
I need to recover some data of the 'home' directory after kernel panic.I was upgrading ubuntu 11.04, [COLOR=blue !important][COLOR=blue !important]installed[/COLOR][/COLOR] on usb.Failed to upgrade because the main partition had no more space. I moved one directory of about 100Mb to other partition, but it seemed that in the main partition didn't appear those 100Mb free. i restarted the computer expecting those 100Mb free. And kernel panic.

"press tab in the welcome bootscreen when you are about to select whether to install or restore an existing system and write intel_iommu=off and press enter" but that does not really helps.. it just does the same.. in some blogs they say "upgrade your bios".. but i say.. then why i can not install the olders distributions with my "old" bios.
